UPP Examples, EvmA - EvmB fails

Mitch Nelson
Expert 1440 points

The Problem:

UPP loop example succeeds

UPP EvmA<->EvmB  fails.

Here is a more complete description

The environment is CCS4 with BIOS 5 and BIOS 6 packages installed, including BIOS5 and current (BIOS6) versions PSP and EDMA3, and current versions of NDK, and NSP.

The UPP examples are imported into CCS4 from PSP 1.30.01 and built per the procedure described in   http://e2e.ti.com/support/embedded/f/355/t/108905.aspx

The two EVM units are cabled as described in the document "C6748 BIOS PSP User Guide 01.30.01" on  page 258 using breakout boards.  The connections were checked ("buzzed") and then the breakout boards were seated in their sockets on the EVM units.

The examples were loaded and run with the following results:

1.  UPP loop example succeeds

The Printf Log shows messages that report the UPP request, the data comparison, and that it succeeded,.

2. UPP EvmA<->EvmB  fails. 

The Printf Log for EvmA reports two UPP requests, nothing after that.   The Print Log for  EvmB reports one UPP request, and nothing after that.

    Hi Mitch,

     

    Can you execute/run the binaries which comes ready with the BIOS PSP 1.30.01?.

    Placed in: (pspdrivers_01_30_01\packages\ti\pspiom\examples\evm6748\uppEvm\evmA\bin\Debug) and (pspdrivers_01_30_01\packages\ti\pspiom\examples\evm6748\uppEvm\evmB\bin\Debug)

    Do not build any of the projects. Just test the readily available executables which comes with PSP 1.30.01. This is just to isolate the build issue and check if there is any other issue.

     

    Please test this, and let us know the results.

     

    Thanks & regards,

    Raghavendra
